Re: Top pullers, I need help with a bolt

If you are talking the bell housing bolt closest to the firewall, it is a 15 mm socket. Find the shortest ratchet/socket combo you have and see if it clears the space. I am not sure if a 15mm wrench can work, but if you get it on the bolt head, hook another long wrench onto it for more leverage.

The other thing you could try is removing the water crossover for some extra room..........

Thank for the heads up.
I Took a good hard look at my own N* to locate the bolt in question. I found it easy enough but the two bell housing bolts at the top, under the crossover, were completely backed out of their respective threads, just hanging loose like they were never threaded in. The threads on the bolts were clean; the bolt head had no tool scratches and looked like brand new bolts. I am not sure what to make of it???? 117k miles on a one-owner car that has never had the engine removed. Wow I wonder if the car made off the assembly line that way?
